ZRERASE is also related to FI/D safehouse LIMESA in some way.) Refers to HMMA 22207 - can't find it at MFF. "Note with interest two indications on chart sent ref. Would appear burst transmissions resumed. Recommend any subsequent charts on hand in order see if there are any further indications of activity. Advise. 2. Leave aperiodic and recorders in LIMESA. Cable date and time any reactions observed. KUCLUB techs to return HQS per SCMEXI 407. At early date will send Messrs. ___ and ___ to install and leave other equipment LIMESA for further search burst transmissions." (Note that Philip Agee wrote that NSA monitored burst transmissions such as these from USSR to Mexico. http://www.maryferrell.org/showDoc.html?docId=10008&relPageId=66&search="burst_transmissions".) Releasing officer: RA MacMillan - authenticating officer Charles W. Arnold

10/25/63 cable: Message from V. J. Thill at WTON, FI/D/OB, extension 6967 to SCMEXI, citing WTON, in a "special center classified message" re HMMA 22207. "LIMUST...leave aperiodic receiver and recorder in operation. Require soonest any indication that burst transmissions reactivated...will not dispatch techs or gear until some firm evidence from MEXI or ODINCH/NSA that activity renewed. AEGENERATE: In absence of any info contrary consider aperiodic receiver and ZRERASE coverage to date sufficient to conclude AEGENERATE not communicating from his shop." (Note that Philip Agee wrote that NSA monitored burst transmissions such as these from USSR to Mexico. http://www.maryferrell.org/showDoc.html?docId=10008&relPageId=66&search="burst_transmissions".)
104-10150-10003: RECEIVER RESULTS NEGATIVE, CONSIDERED ADEQUATE.
10/25/63: This is the second page of the previous cable. The new chief of FI/D, Ronald A. MacMillan, is listed as the releasing officer. Discussion was about an operation called AEMIQUELET: "Aperiodic receiver results negative and considered adequate. When station receives suitable LP (listening post) techs will be sent to provide ZRERASE (Cuba?) coverage. Would appreciate effort establish AEMIQUELET movements in target in order determine patterns of presence and absence." Appears that the Mexico City station wanted more coverage on the Cuban compound, and maybe the Soviet compound as well. All in the wake of the Oswald events in Mexico City a few weeks earlier.
104-10017-10082: PLANS AND PROGRESS OUTLINED AND APPROVED FOR INTERROGATING ALVARADO
12/3/63 cable DIR 86621 from C/WH/3 John Scelso/John Whitten to Mexico City: "Chief of Station comment: Station outlined plan to borrow Alvarado for questioning." Scelso/Whitten: "...As to the site, we would prefer hotel because from here we cannot judge security factors that might affect use of ZRERASE house; cannot overlook possibility that site might later become public..."

9/29/64: Note stating that LIMESA operations suspended and all gear was being removed. Refers to file "ZRERASE/LIMESA" This suspension coincided with the release of the Warren Report, which was going to reveal a portion of the Mexico City activities. Another memo mentions ZRERASE had a "former safehouse" - was that LIMESA? http://www.maryferrell.org/showDoc.html?docId=4371&relPageId=3&search=zrerase
